Can't do 2k at 60fps but 4k at 60fps

[jared.micheal.larson]

My GTX 1080 can do 1080p60fps and 4k60fps, but 1440p can only go up to 30fps? Does anyone know why? I haven't overclocked or done anything to it really except for driver updates. I have tried uping the DSR-Factor to 4x native resolution, but that only gives me the option of doing 8k. Please help

Vsync on? Same settings used on all res?

its not about in game settings, it just locks it at 30 when running at 1440p
